VALVE-REMOVER.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed. February 13, 1907. Serial No. 357,148.

To all whom it may concern:

Be it known that I, HARRY Z. WHITE, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Valve-Removers, of whichthe following is a specification, reference being had therein to theaccompanying drawing.

My invention relates to devices intended for use in removing valves frommotors, and has for its primary object the provision of means forrelieving the pressure of the valve-spring pending its removal from thevalve-stem; a further object is to make a structure which shall beaccessible to the valve parts when pipes or other impediments areadjacent such parts; also to render the parts adjustable; and finally,to provide a device which is inexpensive, simple, and strong.

To the above ends essentially my invention consists in the novelconstruction and combination of parts hereinafter set forth, andillustrated in the accompanying drawings, wherein Figure l is aperspective view of a device embodying my invention. Fig. 2, a sectionof the same on line x a: of Fig. 1, showing a part of the chain inelevation. Fig. 3, a bottom view of the same. Figs. 4 and 5, side andedge elevations respectively of a section of the chain. Fig. 6, asection of the lever bar on line y y of Fig. 1, and Fig. 7, a sideelevation of my device showing the same in operative position upon avalve.

Like reference characters indicate like parts throughout the views. a

The preferred embodiment of my invention comprises a flat bar, 1, with areduced end portion, 2, which serves as a handle. In place of thereduced portion any convenient grasping means may be applied, or suchreduction may be omitted if the body The end of the bar opposite thehandle is bifurcated forming a central longitudinal slot, 3; and the endof the bifurcated portion is upturned at substantially right angles tothe plane of the bar, forming two tapering V shaped projections, 4, 4.

Through the body of the bar are a plurality of oblong openings, 5, inlongitudinal alinement with each other. In detail each opening comprisesan oblong rectangular portion, 6, terminating in a curved portion, 7, ofgreater diameter than the breadth of the rectangular portion. The lowerface of the bar has circular inwardly beveled countersunk portions orseats, 8, adjacent and merging into the rectangular portions, 6. Whilethe described openings are of preferred form, their outline may bevaried, but it is essential that, when the form of chain used is thathereinafter described, one part of the opening be more restricted inarea than the other portion. An operative but correspondingly lessuseful structure may comprise only one opening.

the circular portion, 7, of the openings, 5.

In conjunction with the described bar is used a curved bearing member orhook, 9, preferably terminating in a point, 10, to which is attached achain, 11, whose links, 12, are of irregular contour. The end of thechain may be free, as shown in Fig. l, or attached to hook 13, orotherwise removably fixed to some portion of the bar body, as shown inFig. 7.

The chain shown comprises links which consist of a flat body, 14,provided with an opening, 15, .therethrough. The upper part of the linkis narrower and thicker than the body, forming a head, 16, with an'opening or passage, 17, transversely disposed with relation to theopening, 15, and receiving the end of the adjacent link. The portions,6, of the openings are sufl iciently broad to permit the entrance of theflat portions, 14, of the links, but too narrow to allow passage of theheads, 16; although the heads can readily traverse When the chain linksare in engaged position the head, 16, of the link rests against the seator shoulder, 8, providing the chain is under tension, and forms, as willbe later shown, a fulcrum point for the lever bar, 1. l

The operation of my device is shown in conjunction with a gasolene motorcylinder, 19, equipped with the valve, 20, stem 21, valve spring, 22,washer, 23, and supporting pin, 24; all of usual form. My remover isoperated as follows: The point, 10, of the member, 9, rests upon thecenter of the valve, 21, in whose upper surface usually exists a smallcavity. The bar, 1, is adjusted at the desired height upon the chain bypushing a link into the restricted portion of the opening, 5. The endsof the projections, 4, are placed against the lower face of the washer,23, in which position the valve stem, 21, is in alinement with the slot,3. The handle, 2, of the bar, 1, is manually depressed whereby thevalve-spring, 22, is compressed, and the pressure thereby removed fromthe retaining pin, 24, whereupon the operator is enabled to withdraw thelatter, and release the valve parts.

By the use of a chain or other flexible element as a connecting elementof the device, the pipes or other obstructions on or adjacent the valvecylinder, do not prevent the necessary leverage of the bar. Theplurality of openings, 5, afford any desired change of fulcrum point.And the seats, 8, assist in retaining the chain in engaged position whentension upon the chain is lessened.

What I claim is,

1. in a valve remover, the combination with a lever bar provided with anoblong opening of greater width at one end than at the other, of abearing member, and a chain attached to the bearing member ofsuflileient dimensions to slide through the broader end of the opening,but not slidable in the narrow portion of the opening.

In a valve remover the combination with a lever bar provided with anoblong; opening of greater width at one end than at the other, of abearing member, and a chain attached to the bearing member slidablethrough a portion of said opening, and comprising links having thin bodyportions and thick head portions.

3;. In a valve remover the combination with a lever bar provided with anirr gular opening of greater width at one end than at the other andhaving a countersunk portion upon the under face of the bar merging intoa portion of the opening, of a bearing member and a chain upon thebearing member adapted to traverse a portion of said opening, the chaincomprising links provided with thick head portions adapted to rest inthe countersunk portion of the bar when tension is applied to the chain.

4-. In a valve remover the combination with a lever bar provided with anopening of irregular dimensions, of a bearing member. and a chainattached to the bearing member slidable through a portion of saidopening but nonslidable through another portion of said opening 5. In avalve remover the combination with a lever-bar provided with an openingof irregular dimensions, of a bearing member, and a flexible memberattached to the bearing member slidable through a portion of saidopening, but non-slidable through another portion of said opening.

64 In a valve remover the combination with a lever-bar provided with anopening of a bearing member. and -a flexible member attached to thebearing member and slid" able through the opening of the lever-ban T. Ina valve remover, the combination with a lever-bar provided with alongitudinal slot in one end. olf angular prongs upon the lever havingtheir anguL-ir portions upon each side 01 the slot. a bearing member. aflexible member attached to the bearing member, and means upon theflexible member for i'ulcruming the lever-bar.

S. In a valve remover the combination with a lever-bar provided with anopening. of a bearing member and a flexible member attached to thebearing member slidable through a portion of said opening butnon-slidable through another portion of said opening.

In testimony whereof I have atlixed my signature in presence 01 twowitnesses.
